Lithium battery vacuum drying oven temperature acquisition and control device

Abstract

The invention provides a lithium battery vacuum drying oven temperature acquisition and control device, which comprises a temperature acquisition module, a temperature control module and an integratedcontrol system, wherein the temperature acquisition module is a multipath temperature acquisition integrated control system and is used in a high-temperature and high-vacuum state; the temperature acquisition module is connected with the temperature control module, and the temperature acquisition module converts physical characteristic signals to digital temperature signals and outputs the digital temperature signals to the temperature control module; and the integrated control system is connected with the temperature control module, the integrated control system receives a sending instruction and carries out temperature control on the temperature control module, and the integrated control system monitors the temperature acquired by the temperature acquisition module in real time. Throughintegrating a solid state relay and a thyristor by the temperature control module, the integrated control system can control heating of each heating plate at any time; and through integrating the solid state relay and the thyristor to the temperature control module, the line layout is greatly simplified, the line is clearer, and the maintainability is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of lithium battery automatic baking lines, and in particular relates to a temperature acquisition and control device for a lithium battery vacuum drying oven. Background technique [0002] The existing lithium battery vacuum drying oven temperature acquisition and control device has the following disadvantages: [0003] 1. The design of multi-channel temperature acquisition and control circuit is complicated, which is not conducive to the interchangeability of fixtures in the production process. [0004] 2. The temperature control module on the vacuum drying oven will always be in the temperature control mode as long as there is a load, causing the solid state relay to continue to work, reducing the service life, and cannot realize independent control of a single heating plate. [0005] 3. The solid-state relay is independent of the temperature control module, resulting in a large space occupied by the circ...
